Filed Apr. 28, 1961, Ser, No. 106,316 3 Claims. (Cl. 16-95) This invention relates generally to folding doors for telephone booths and particularly to improved means for supporting and guiding such a door.

When the door of a telephone booth is unsupported except by hinges connecting the door to a corner post of the booth, the load on the hinges connecting the door to the corner post and the load on the hinges between the door sections is great and the friction between hinge parts causes them to wear to such an extent that occasionally the guide which controls the folding action of the door drops out of the guideway, and control of the folding action of the door is lost. The same thing may happen when the door is subjected to an excessive load, even if the hinges are not worn. Even before the guide drops out of the guideway, the door may sag out of square with the front posts and become very difl'lcult to operate properly. Accordingly, an object of the invention is to provide a door guide which cannot be dislodged from the guideway.

Another object is to provide door guide means which relieves the door hinges of a material portion of the weight of the door and thereby prevents excessive wear and tear on the door hinges.

Other objects of the invention will become apparent when the following description is read with reference to the accompanying drawings, in which:

FIGURE 1 is a vertical section looking from Within a telephone booth at the front wall thereof;

FIGURE 2 is a horizontal section on the plane indicated by line 22 of FIGURE 1, but showing the door guide means, part being broken away; and

FIGURES 3, 4, and 6 are enlarged vertical sections respectively on lines 33, 44, 5-5 and 6-6 of FIG- URE 2.

Referring particularly to FIGURES 1, 2 and 5, a tele-' phone booth constructed in accordance with the invention comprises upright corner posts lll and 12, a lintel 14 extending horizontally between the upper end portions of the corner posts, and a root 16. In a doorway defined by the lintel 14 and the corner posts and '12 is a door having two sections 18 and 20 joined together by a piano hinge 22. The door is hung on the corner post 10 by a plurality of hinges 24 aflixed to the section 18. The section 20 mounts mobile door guide means, generally designated 26, and immediately above the top of the door is stationary door guide means, generally designated 28. The booth is equipped with a ceiling structure, generally designated 30.

Referring particularly to FIGURES 4 and 6, the door section '20 carries a-bracket having a main body 36 and a flange '38 secured to the door section 20 by means of screws 40. Threaded into the body 36 is the lower end portion of an upright bolt 42 provided with a head 44.

Revolvably mounted upon the bolt 42 is a guide roller 46 seated directly upon the body 36. At the upper end of the bolt 42 is a firame provided with a crosshead 48 and a stem 50 depending from the cross'head. This firame is provided with an opening 52. The bolt 42 extends through the opening 52 and may be turned therein. Projecting outwardly from each end of the crosshead 48 is a pin 54 mounting a roller 56.

The stationary door guide means 28 comprises a section 58 and a section 60 spaced from one another to pro- ,ttes atent O F 3,046,594 Patented July 31,1962

. 2 vide a guideway 62 extending from the proximity of the post 12 rearwardly toward the other side of the booth. The section 58 comprises a lower horizontally exten 'dmg plate 64 extending from the guideway :62 to the front wall of the booth where it is provided with an upturned flange 66 and toward one side of the section 58 where it is provided with an upturned flange 67. Seated upon the plate 64 is a Z-shaped spacer plate 68 extending along flange 66, a Z-shaped spacer plate 69 extending along flange 67 and a channel-shaped spacer plate 70 extending along the guideway 62. Overlying the spacer plates 68 and 70 is a horizontally extending upper plate 72 having an upturned flange 74 over the spacer plate 68, upturned flange 75 over the spacer plate 69* and a flange '76 turned downwardly over the spacer plate 70, the flange 76 being provided with an oflset portion 78 upon which is seated the marginal portion of the plate 64 extending along the guideway '62. interposed between the flanges 66 and 74 is the lower end of a hanger plate 80 suitably affixed to the lintel @14 and interposed between the flanges 67 and 75 is the lower end portion of a plate hanger 82 suitably secured to the roof structure.

The section 60 of the door guide means 28 is provided with a lower plate 84 extending from the guideway 62 rearwardly to the ceiling structure 30, where it is provided with an upstanding flange 86 terminating in a horizontally extending marginal portion 88, and toward one side of the section 60, where it is provided with an upturned flange 90. Seated upon the plate 84 is a spacer channel 92 extending along the guideway 62. Overlying the spacer channel 92 and the flange 86 is an upper plate 94 having a downwardly turned flange 96 adjacent the flange 90. Plate 94 is also provided with a flange 98 turned downwardly over the spacer channel 92, and provided with an offset portion 100 upon which is seated the marginal portion of the plate 84 extending along the guideway 62. Interposed between the flanges and 96 is the lower end portion of a hanger plate 102 aflixed by its upper end to the roof structure. The flange portion 88 of the plate '84 is secured to the overlying marginal portion of the plate 94. At each end of the guideway 62 is a U-shaped strap 104 extending downwardly into the guideway, being fixed in position by screws 106. Underlying the strap is a rubber bumper 108 afiixed to the strap as by a screw "110. I

Overlying the guideway 62 a cover plate 112 secured to the upper plates '72 and 94, as by screws 114.

When the door of the booth is closed and it desired to gain access to the interior of the booth, the door is opened by placing the band near the center of the door and pushing inwardly, whereupon the door section 18 swings into the booth about the or" the hinges 24 from the full line to'the broken line position shown in FIGURE 2. Simultaneously, the door section 20 swings counterclockwise, as viewed in FIGURE 2, about the axis of the hinge 22 from the full line to the broken line position shown in FIGURE 2, and folds over the door section 18, being controlled by movement of the hinge 22 clockwise in an arcuate path and by movement 01 the roller 46 in the way 62 between the flanges 76 and 98.

At the same time, the door is supported by the mobile door guide means 26, the rollers 56 moving over the plates 72 and 94 in contact therewith.

When the door swings open, the bolt 42 being fixed 7 door itself weighs or how great the load thereon, the mobile door guide means 26 cannot be dislodged from the guideway 62, and that in any position of the door, the door is fully supported. Thus wear and tear on the hinges of the door is reduced to a minimum, and the door cannot sag out of square with the front posts of the booth.

It will be understood, of course, that the present invention is susceptible of various modifications which may be made without departing from the general principles of the invention. Accordingly, it is intended to claim the same broadly as well as specifically as indicated by the appended claims.

What is claimed is:

1. In a telephone booth, a door including a plurality of folding sections, a pair of stationary partition members having upper surfaces extending in a horizontal plane above said door, said members having spaced mutually facing edges defining vertical sides of a horizontally extending guideway, a carriage having arm portions extending laterally above said guideway and a depending portion of rectangular cross-section extending downwardly into said guideway, a roller journaled for rotation on each of said arm portions, said rollers bearing against said upper surfaces of said partitioned members on opposite sides of said guideway and, a swivel support member interconnecting one of said door sections and said carriage so that said carriage and rollers transmit the weight of said door to said partitioned members and said depending portion of said carriage maintains said rollers in fixed angular position with respect to said guideway.

2. The structure as claimed in claim 1 wherein said swivel support member comprises a bolt having an upper slotted head portion journalled in and supported by said carriage and a lower threaded portion secured to said door section.

3. The structure as claimed in claim 1 further including, a pair of flanges depending from said partition members on opposite sides of said guideway and, a roller journaled on said support member and engaging said flanges for preventing lateral movement of said door with respect to said guideway.
